Dedicated to the balanced discussion of global warming
The Independent – June 27, 2008
There is a very real chance that there will be no ice at the North Pole this summer. This is probably being caused by a “perfect storm” of several events including a slight warming of the Arctic Ocean, a slight warming of the air above the ocean, a change in ocean currents, a change in prevailing winds and possibly even the ozone layer. It is important to note that this does not mean that there is no ice in the Arctic Ocean as it appears that the water off the coast of Canada and Greenland will be ice covered.
If the lack of ice was solely due to warming, you would expect that the North Pole would be the last to thaw. Since other factors are in play, the thawing is uneven.
The disappearance of the Arctic sea ice, making it possible to reach the Pole sailing in a boat through open water, would be one of the most dramatic – and worrying – examples of the impact of global warming on the planet. Scientists say the ice at 90 degrees north may well have melted away by the summer.
Seasoned polar scientists believe the chances of a totally ice-free North Pole this summer are greater than 50:50 because the normally thick ice formed over many years at the Pole has been blown away and replaced by huge swathes of thinner ice formed over a single year.
The polar regions are experiencing the most dramatic increase in average temperatures due to global warming and scientists fear that as more sea ice is lost, the darker, open ocean will absorb more heat and raise local temperatures even further. Professor Peter Wadhams of Cambridge University, who was one of the first civilian scientists to sail underneath the Arctic sea ice in a Royal Navy submarine, said that the conditions are ripe for an unprecedented melting of the ice at the North Pole.
